Specification of Letters Patent.

Patented Apr. 15, 1919.

Application tiled May 3, 19118. Serial No. 232,258.

To all whom t may concern:

Be it known that I, NATHANRUBENSTEIN, a citizen o-f the United States, and a resident of New York, borough of BronX, in the county of Bronx and State of New York, have made and invented certain new and useful Improvements in Machines for Facilitating the Unrolling of Cloth from Cloth Bolts, of which the following is a specification.

My invention lrelates to machines Vdesigned particularly for use by manufacturers of clothing and in similar trades, the purpose thereof being to provide a machine whereby cloth may be readily unwound from the cloth bolt or roll in which it is ordinarily sold and laid upon a table preparatory to cutting the garment or other article to befproduced therefrom, by the use of a suitable pattern; the usual practice in themanufacture of clothing or other articles from cloth being to unroll the cloth from a bolt or roll and pile lit in several thicknesses upon a table, afterwhich a plurality of pieces from which the garment or other article is formed are cut out at a single time from the pile of cloth thus accumulated.

The object of my invention is to provide an improved machine of the type or class above referred to and for the purpose pointed out in which the cloth bolt or roll is supported and held in a vertical position while the cloth is being unrolled, `and in which the bolt or roll may be easily removed from the machine and another substituted therefor, should occasion arise for the use of another kind of cloth. More particularly stated, my invention contemplates and the object, thereof is to provide a clot-hunwinding machine in which a read-ily removable portionof the machine is designed to remain within the bolt or roll until the cloth is all used therefrom; the machine in question being commonly provided with a plurality of such removable portions which remain Vwithin the bolt, in order to provide for the use of diferent kinds of cloth from `different bolts or rolls, `and for the interchange of bolts o r rolls with adminimum of delay and" inconvenience It,will, however, be appreciatedthat a given machine made in accordance with my invention may be provided with oneonly of the removable elements which enter into and serve to hold the bolt or roll in an upright p0sition,. in case cloth all of one kind is to be used.

A further object ofmy invention is to provide a cloth unwinding or unrolling machine of the type or class above referred to which will be simple in construction and easily portable, so that it may be placed in proximity with the table or other support upon which the cloth is laid preparatory to being cut into suitable shapes from a pattern; the said machinefbeing simple in construction, easy to manufacture, and eective for the purpose for which it is designed.

With the above and other objects in'view, my invention consists inl the machine for facilitating the unwinding or unrolling of cloth from the bolt or roll illustrated in its preferred form in the accompanying drawings, described in the following specification, and particularly claimed, and in such variations and modifications thereof as will be obvious to those `skilled in the art to which my invention relates.

The drawings accompanying and forming a part of this specification illustrate what I regard as the preferred embodiment of my invention, the same being shown in two forms, differing somewhat from each other, so far as concerns the manner in which the machine is'supported from a suitable support; 'although it will be appreciated that my invention may be embodied in various other specific forms, and that the same includes all such embodiments thereof as come within the scope of the Vconcluding claims wherein the particular features kin which my invention consists 'are particularly pointed out.

Referring to the drawings:

Y Figure l is a view illustrating my improved cloth unwinding machine in plan, and attached to a suitable table;

Fig. 2 is a view showing a section of the same taken upon a vertically-extending plane indicated by the line 2-2 of Fig. 1;

Fig. 3 is a view showing in side elevation a modified form of the element of the Inachine used to hold the cloth bolt in an upright position;

Fig. lis a perspective view illustrating a form of my invention in which a different form of supporting member or base for supporting the. machine is employed; and Fig. 5 is a fragmentary view illustrating certa-in features of the form of my invention illustrated in Fig. 4t upon a larger scale, and more in detail, than in said iigure.

Referring first to the embodiment of my invention illustrated in Figs. l and 2, the same is shown as comprising a suitable supporting member or base 7 designed to be clamped to a table 8 by means of a screw 9, the upper portion of said supporting member being hollow as indicated at 10, and having two bearings 11, 12, spaced apart and arranged one above the other as shown; the upper of these bearings 12 being preferably in the form of a removable bushing in threaded engagement with the upper end of the opening 10, in order that the supporting shaft to be hereinafter referred to may -be readily assembled with the base and held in proper position in the machine.

The reference numeral 13 designates a horizontally arranged table rotatable about a vertical axis, which table is supported fromand above the-supporting member 7 and in turn serves as a support for the cloth bolt or roll from which the cloth is to be unwo'und; the supporting of the table being illustrated as accomplished by the use of a vertically extending shaft 14 rotatable Iin theV bearings 11, 12 above referred to, and which shaft extends upward through the table and to some little distance above the upper surface thereof, asbest shown in Fig. 2.l rlhe table 13 is shown as in threaded engagement with the shaft at 15, so that the two rotate together; and a nut 16 is provided which is in threaded engagement with the shaft and serves, in the embodiment of my invention illustrated, to hold the table and shaft together in a rigid and permanent manner. The shaft 15 is provided with an opening adapted to receive a transversely extending pin 17, which pin, when the parts are assembled, lies in close proximity with the lower end of the bushing 12 and thus holds the shafty in proper position within the bearings aforesaid and relative to the supporting member or base. It will be lappreciated, however, that the details of the manner in which the rotating table is supported from the supporting member may be varied.considerably without departing from thefspirit of my invention, as the same is pointed out and defined in the claims at the v end of this specication.

The reference numeral 18 designates as a whole a vertically extending bolt supporting member supported from the table 13 and extending upwardly therefrom, and adapted to enter a cloth bolt 19 between the inner layer of cloth and the board 20 upon which the cloth is wound, as shown in Figs. land 2; the purpose of the said supporting member being to hold the cloth bolt in an up right position, so that the same may rotate about a vertical axis in unwinding the cloth. This bolt-supporting member is shown as made up of two portions, the upper of which is in the form of a spindle 21, while the lower portion is in the form of a hollow sleeve 22; whereby a longitudinally extending passage is provided at the lower end being preferably provided at the lower end of the sleeve in order to provide an extended bearing surface and a steadier support for the cloth bolt or roll.

It will be appreciated that the features of construction of the bolt supporting member above described provide a scheme in which the cloth bolt, together with the bolt sup porting member contained within the same, may be readily removed .from the supporting table and a new bolt of another kind of .cloth and having another bolt supporting `memberwithin the same substituted there for; thus providing for the interchange of cloth bolts, and for-the use of various kinds Vof cloth, accordingto the requirements'of the user, with a minimum of troubleV and expense and by the use of aV single machine equipped, however, with a plurality of interchangeable bolt supporting members.

VThe upper end of the bolt supporting member illustrated in Figs. l and 2 is shown as provided with' a steadying member 211, shown as inthe'form o f a ring, although the form of steadying member is of second ary importance; thev purpose of this member being to. prevent the bolt from tipping, or, as otherwise expressed, to hold the central spindle portion ofthe bolt-supporting member centrally within the cloth-bolt; it being appreciated that were this element 'not employed the upper end of the bolt supporting member might tend to move laterally along the board 20 to one edge or the other thereof, which would result in a wabbling motionof the bolt as the cloth was unwound, and'might otherwisevinterfere with the unrolling of the cloth.

Fig. 3 shows a form ofbolt supporting member interchangeable with the table and shaft shown in Figs. 1 and'2, this form of supporting member being especially adapted for usein4 unwinding cloth or similar fabric from a circular bolt, z'. c., one in which theV ,base different from thatV illustrated in Figs.

1 and 2 is employed, the form of base illustratedinthis ligure being designed to rest upon a table, or shelf, or even upon the iioor, without, however, being clamped `to the member upon which it rests. i

Inthis form of my invention, the rotating table 28 and vertically extending cloth bolt supporting member or spindle 29 `areor may be of the same form and construction as the table and spindle hereinbefore referred to in describing the embodiment of my' `invention illustrated in Figs. 1 and 2. The vertically extending shaft 30, which carries the table 28, is also shown as of the same form as hereinbefore described, the lower end thereof being illustrated as supported in spaced bearings 31, 32, provided in a suitable base 4, the upper of said bearings being in threaded engagement with the upper end of an opening 33 provided in the base whereby the machine as a whole is supported, the shaft being held in place by means of a transversely extending pin 35, as hereinbefore explained.

'In the embodiment of my invention illustrated in these figures, the base 34 is formed as a single casting and is provided with a plurality of radially extending arms 36 having feet 37, made preferably of rubber, at their extremities, whereby the base is prevented from slipping. The form of base described obviously provides an extended support for the table 28 and cloth bolt supported thereby, and thus provides a somewhat more stable machine than that illustrated in Fig. 1, and at the same time provides a machine which may be conveniently moved about from one place to another, as it is not necessary to clamp the same to a table or other support preparatory to using the machine, as is the case in the embodiment illustrated in Figs. l and 2.

The radially extending arms 36 of the base are shown as and are preferably provided each with a roller 38 supported in suitable bearings 39, and the peripheries of which rollers are adapted to engage with the under side of the table 28, whereby the same is prevented from tipping and is somewhat more steadily supported; as it will be obvious that there is commonly more or less looseness and lost motion between the vertically extending shaft 30 and the bearing in the base in which it is supported, which looseness, however, is counteracted by the rollers and a more steady support for the table thus secured, as will be appreciated.

Having thus described and explained my invention, I claim and desire to secure by Letters Patent:
